This is because the default WM_ERASEBKGND handling occurs, which erases the entire invalidated area with the default (white) brush, pointlessly, before the entire invalidated area is bitblt'ed from the shadow framebuffer. Attached patch causes WM_ERASEBKGND handling to be skippped. 34512 yselkowitz 2009-02-12 19:58:20 +0000 Patch in the queue for 1.5.3-7. 34681 yselkowitz 2009-02-22 19:16:11 +0000 Pushed in 1.5.3-7; closing. 3733 2009-02-12 18:18:00 +0000 2009-02-12 18:18:35 +0000 Patch to reduce resize flickering cygwin-multiwindow-flicker.patch text/plain 2011 jon.turney Q3lnd2luL1g6IEF2b2lkIGEgdmlzdWFsIGdsaXRjaCBvbiB3aW5kb3cgbW92ZSBpbiByb290bGVz cyBtb2RlcwoKSGFuZGxlIGFuZCBpZ25vcmUgV01fRVJBU0VCS0dORCBzaW5jZSB3ZSByZXBhaW50 IHRoZSBlbnRpcmUgaW52YWxpZGF0ZWQgcmVnaW9uIGFueWhvdwoodGhpcyBhdm9pZHMgYSB3aGl0 ZSBmbGlja2VyaW5nIG9uIHdpbmRvdyByZXNpemUpCgotLS0KIHhzZXJ2ZXIvaHcveHdpbi93aW5t dWx0aXdpbmRvd3duZHByb2MuYyAgIHwgICAgOCArKysrKysrKwogeHNlcnZlci9ody94d2luL3dp bndpbjMycm9vdGxlc3N3bmRwcm9jLmMgfCAgIDExICsrKysrKysrKysrCiAyIGZpbGVzIGNoYW5n ZWQsIDE5IGluc2VydGlvbnMoKykKCkluZGV4OiB4b3JnLXNlcnZlci0xLjUuMy94c2VydmVyL2h3 L3h3aW4vd2lubXVsdGl3aW5kb3d3bmRwcm9jLmMKPT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0geG9yZy1zZXJ2ZXIt MS41LjMub3JpZy94c2VydmVyL2h3L3h3aW4vd2lubXVsdGl3aW5kb3d3bmRwcm9jLmMJMjAwOS0w Mi0xMCAyMTo1NTo1NC45MjE4NzUwMDAgKzAwMDAKKysrIHhvcmctc2VydmVyLTEuNS4zL3hzZXJ2 ZXIvaHcveHdpbi93aW5tdWx0aXdpbmRvd3duZHByb2MuYwkyMDA5LTAyLTExIDE0OjExOjMxLjM0 Mzc1MDAwMCArMDAwMApAQCAtNDY4LDYgKzQ2OCwxNCBAQAogICAgICAgSGFuZGxlQ3VzdG9tV01f SU5JVE1FTlUgKCh1bnNpZ25lZCBsb25nKWh3bmQsIHdQYXJhbSk7CiAgICAgICBicmVhazsKIAor ICAgIGNhc2UgV01fRVJBU0VCS0dORDoKKyAgICAgIC8qCisgICAgICAgKiBQcmV0ZW5kIHRoYXQg d2UgZGlkIGVyYXNlIHRoZSBiYWNrZ3JvdW5kIGJ1dCB3ZSBkb24ndCBjYXJlLAorICAgICAgICog c2luY2Ugd2UgcmVwYWludCB0aGUgZW50aXJlIHJlZ2lvbiBhbnlob3cKKyAgICAgICAqIFRoaXMg YXZvaWRzIHNvbWUgZmxpY2tlcmluZyB3aGVuIHJlc2l6aW5nLgorICAgICAgICovCisgICAgICBy ZXR1cm4gVFJVRTsKKwogICAgIGNhc2UgV01fUEFJTlQ6CiAgICAgICAvKiBPbmx5IHBhaW50IGlm IG91ciB3aW5kb3cgaGFuZGxlIGlzIHZhbGlkICovCiAgICAgICBpZiAoaHduZFNjcmVlbiA9PSBO VUxMKQpJbmRleDogeG9yZy1zZXJ2ZXItMS41LjMveHNlcnZlci9ody94d2luL3dpbndpbjMycm9v dGxlc3N3bmRwcm9jLmMKPT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0geG9yZy1zZXJ2ZXItMS41LjMub3JpZy94c2Vy dmVyL2h3L3h3aW4vd2lud2luMzJyb290bGVzc3duZHByb2MuYwkyMDA5LTAyLTEwIDIxOjU1OjU0 LjY1NjI1MDAwMCArMDAwMAorKysgeG9yZy1zZXJ2ZXItMS41LjMveHNlcnZlci9ody94d2luL3dp bndpbjMycm9vdGxlc3N3bmRwcm9jLmMJMjAwOS0wMi0xMCAyMTo1NTo1Ni41OTM3NTAwMDAgKzAw MDAKQEAgLTc3OSw2ICs3NzksMTcgQEAKICAgICAgIFNlbmRNZXNzYWdlIChod25kU2NyZWVuLCBt ZXNzYWdlLCB3UGFyYW0sIGxQYXJhbSk7CiAgICAgICByZXR1cm4gMDsKIAorICAgIGNhc2UgV01f RVJBU0VCS0dORDoKKyNpZiBDWUdERUJVRworICAgICAgd2luRGVidWcgKCJ3aW5NV0V4dFdNV2lu ZG93UHJvYyAtIFdNX0VSQVNFQktHTkRcbiIpOworI2VuZGlmCisgICAgICAvKgorICAgICAgICog UHJldGVuZCB0aGF0IHdlIGRpZCBlcmFzZSB0aGUgYmFja2dyb3VuZCBidXQgd2UgZG9uJ3QgY2Fy ZSwKKyAgICAgICAqIHNpbmNlIHdlIHJlcGFpbnQgdGhlIGVudGlyZSByZWdpb24gYW55aG93Cisg ICAgICAgKiBUaGlzIGF2b2lkcyBzb21lIGZsaWNrZXJpbmcgd2hlbiByZXNpemluZy4KKyAgICAg ICAqLworICAgICAgcmV0dXJuIFRSVUU7CisKICAgICBjYXNlIFdNX1BBSU5UOgogICAgIAogICAg ICAgLyogQmVnaW5QYWludCBnaXZlcyB1cyBhbiBoZGMgdGhhdCBjbGlwcyB0byB0aGUgaW52YWxp ZGF0ZWQgcmVnaW9uICovCg==
